I don't see the "pentagram" that you point out. Even when you highlighted it, I still didn't really see it. What I can do for you though, is point
out 2 other things:
1. If it is a pentagram...
It apparently is hiding out on the Mount of Luna (or the Moon). Any book on Cheiromancy, Cheirognomy, or palmistry for the layman would point out the
meaning of this mark:
The star on the mount of luna is, according to my system, a sign of great celebrity arising from the qualities of the mount, namely, through
the imaginative faculties... There is another meaning, however, to this sign, which may have given rise to this idea, and that is that when the line
of the head ends in a star on this mount the dreamy imaginative faculties will ruin the balance of the line of the head, and the result will be
insanity...

So, if your star is where you say it is, then you've got an active imagination, which may tend to emotionally cloud your judgments. Which means you
might sometimes experience bouts of depression, rage, or aloofness.
If you don't have a star where you seem to believe, then you probably wouldn't experience any of those.
2. The Cross of Saint Andrew
In your pictures, just left and above where you see the pentagram are two diagonal crossing lines. They form an elongated X just above your wrist,
center of your palm. This is typically called The Cross of Saint Andrew by those of us who read palms. We consider it important for two factors:
• It signifies someone who can save a life: a paramedic, or good Samaritan, even generous and philanthropic people typically have a pronounced Cross
on their palms.
• It also could signify that you value others' lives before your own. In the line of duty you'll make sure everyone else is safe before
yourself.
Just something to think about. Maybe you don't have a "protection pentagram" on your hand, but you might have the "life-saver" X on your palm.
